This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

5 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Certn's market positioning leverages technology to disrupt traditional background checks by offering automated, online, and API-driven solutions. Their business model focuses on SaaS delivery with tiered packages for different business sizes and industries, including retail, healthcare, technology, and staffing. The company maintains a strong partnership ecosystem, linking to services like MyCRC for individual checks and providing extensive developer resources. Revenue streams likely include subscription plans, volume-based pricing, and partner integrations. Growth indicators include active AB testing, session recordings, and extensive marketing analytics. Strategic observations highlight a focus on seamless integrations and user-friendly experiences to reduce hiring friction and costs.

Security posture

Certn exhibits a mature security posture with mandatory HTTPS, domain transfer lock, and no visible exposure of sensitive data. The use of reputable third-party services for analytics and marketing is balanced with privacy compliance efforts, including cookie consent banners and privacy policies. However, the absence of a dedicated security policy, incident response information, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. The lack of DNSSEC and some security headers suggests potential enhancements to harden the site against DNS and web-based attacks. Overall, the security maturity is good but could be elevated with formalized policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement and publish a comprehensive security policy and incident response plan on the website.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance browser security.
  4. Create a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is powered by WordPress CMS with a modern and well-maintained tech stack including jQuery, Google Tag Manager, HubSpot, and other marketing and analytics tools. Performance is optimized with lazy loading, preconnects, and CDN usage. The site is mobile-optimized and accessible with clear navigation and structured content. Technical debt appears low, with active use of AB testing and session recording tools indicating ongoing optimization efforts. Opportunities exist to further modernize security controls and enhance DNS security. The infrastructure is robust and supports the business's digital marketing and operational needs effectively.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
